IMPROVEMENT IN BUCK-SAW FRAMES.

Specification forming part of Letters Patent No. 118,233, dated August22, 1871.

To all whom it may concern:

Be it known that I, WILLIAM HANKIN, of Hawley, in the county of Wayneand State of Pennsylvania, have invented a new and Improved Buck-SawFrame; and I do hereby declare that the followin g is a full, clear, andexact description thereof, which will enable others skilled in the artto make and use the same, reference being had to the accompanyingdrawing forming part of this specification, in which- Figure 1represents a side view, partly in section, of my iinproved buck-sawframe. Fig. 2 is a detail transverse section ofthe same on the line c o,Fig. 1.

Similar letters of reference indicate corresponding parts.

This invention relates to a new means of bracing buck-saw frames byL-shaped staple-braces itted thron gh the ends of the cross-bar, andbearing against the side pieces ofthe frame.

A A in thedrawing are the side pieces of a buck-saw frame. B is the saw5 G,`the cross-bar in the middle; and D, the upper straining-cord orscrew. E E are two angular wires or metal rods, which are fitted throughapertures at the end of the cross-bar, and bear with theirends againstthe inner sides of the side pieces above and below the crossbar, asshown. The side pieces have sockets provided in them for the receptionofthe ends of the angle or staple-braces E. Metallic washers may beplaced into these sockets to protect the ber of the wood. The cross-barhas tenons a at the ends which enter sockets in the side pieces in theordinary 1nan ner.

Vhen the tightener D on the top of the frame is shortened the sidepieces are drawn against the upper ends of the staple-braces E, wherebytheir lower ends are forced out, moving freely through the cross-bar andstretching the saw.

The lowerI ends ofthe braces E can be carried nearer the saw than anyother bracing device, and a better effect is, consequently, produced.The cross-bar C is at the same time braced above and below, and cannotrack at the shoulders. The entire saw-frame, in fact, becomes rigid,and, having the braces in the center, is balanced. The band on the upperpart of the frame is unobstructed.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The buck-saw frame, provided with the anglebraces EE, which pass through the cross-bar C and bear against the side piecesA, substantially as herein shown and described.

WILLIAM HANKIN.
